Equivalent & Substitute Parts for ISE2409A-H-TR

Part Overview

ISE2409A-H-TR is a DC-DC converter manufactured by XP Power, designed as an isolated module with a single output of 9V at a maximum current of 111mA and input voltage range spanning from 21.6V to 26.4V. The part features a 3 kV isolation rating, is surface-mountable in an 8-SMD Module, and supports an operating temperature range of -40°C to 105°C (with derating). The device is now classified as obsolete, making it necessary to consider alternative models for continued design support or replacement in existing applications. Suitable substitutes must meet all critical electrical and mechanical parameters to ensure direct replacement compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined by strictly matching the electrical and mechanical parameters defined for isolated module DC-DC converters within this product class. Compatibility requires exact or closely matched values for input voltage range (21.6V – 26.4V), output voltage (9V), maximum output current (111mA), output power, isolation voltage (3 kV), package size and configuration (8-SMD Module, 5 Leads), operating temperature range, mounting type, and compliance status including RoHS and MSL. Only parts meeting these specified metrics are listed as substitutes.

Key parameters used for substitute grouping:

• Number of Outputs
• Voltage - Input (Min/Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Voltage - Isolation
• Mounting Type
• Package / Case
• Size / Dimension
• Operating Temperature
• Product Compliance Status (RoHS, MSL)
• Category/Application (ITE Commercial)

Parameter Comparison

Engineering Selection Recommendations

The ISE2409A-H-TR is classified as obsolete, and continued use is limited to remaining inventory. The substitute part PESE1-S24-S9-M-TR from CUI Inc. is active and matches all essential electrical, mechanical, and compliance parameters. Both parts are RoHS compliant with an MSL rating of 1 (unlimited). PESE1-S24-S9-M-TR holds additional agency approvals (CE, cURus) and matches the isolation voltage, output current, voltage ratings, and mounting type.

Frequently Asked Questions (FAQ)

Q1: What are the critical parameters for selecting a substitute DC-DC converter for ISE2409A-H-TR?
A1: The essential parameters are input voltage range (21.6V–26.4V), output voltage (9V), maximum output current (111mA), power rating, isolation voltage (3 kV), package (8-SMD Module, 5 Leads), mounting type, operating temperature range, and compliance (RoHS, MSL).

Q2: Are the mechanical footprints identical for ISE2409A-H-TR and PESE1-S24-S9-M-TR?
A2: Both utilize an 8-SMD Module, 5 Leads configuration. Size and dimension are closely matched, ensuring compatibility at the board level.

Q3: Can PESE1-S24-S9-M-TR be installed in place of ISE2409A-H-TR without changes to the PCB layout?
A3: The substitute shares the same package type and similar dimensions, allowing direct replacement where package compatibility is required.

Q4: What compliance standards should be verified when selecting a substitute?
A4: Both main and substitute parts are RoHS and MSL 1 compliant. The substitute also provides agency approvals (CE, cURus).

Q5: Is there any difference in output power or efficiency between the two parts?
A5: ISE2409A-H-TR specifies 1W power with 80% efficiency. PESE1-S24-S9-M-TR is rated at 999 mW with 83% efficiency. Output voltage and current are identical.

Q6: Are special considerations needed for inventory and product lifecycle?
A6: ISE2409A-H-TR is obsolete. The substitute PESE1-S24-S9-M-TR is in active production, ensuring supply continuity.
